The FW has a watchdog of 200ms in the PNVM load flow, so the driver should have a slightly higher timeout. Change the timeout from 100ms to 250ms. Signed-off-by:

pcim_iomap_table() might return NULL, so we shouldn't unconditionally dereference the return value by taking the [0] entry. Handle this better by checking for NULL first, and then separately checking if the [0] entry is NULL. Signed-off-by:

When we have a P2P Device active, we attempt to only change the PHY context it uses when we get a new remain-on-channel, if the P2P Device is the only user of the PHY context. This is fine if we're switching within a band, but if we're switching bands then the switch implies a removal and re-add of the PHY context, which isn't permitted by the firmware while it's bound to an interface. Fix the code to skip the unbind/release/... cycle only if the band doesn't change (or we have old devices that can switch the band on the fly as well.) Signed-off-by:

One USB data buffer can contain multiple received network packets. If that's the case, they're processed this way: 1. Original buffer is cloned 2. Original buffer is trimmed to contain only the first network packet 3. This first network packet is passed to network stack 4. Cloned buffer is trimmed to eliminate the first network packet 5. Repeat with the cloned buffer until there are no more network packets inside However, if the space remaining in original buffer after the first network packet is not enough to contain at least another network packet descriptor, it is not cloned. The loop parsing this packets ended if remaining space == 0. But if the remaining space was > 0 but < packet descriptor size, another iteration of the loop was done, processing again the previous packet because cloning didn't happen. Moreover, the ownership of this packet had been passed to network stack in the previous iteration. This patch ensures that no extra iteration is done if the remaining size is not enough for one packet, and also avoid the first iteration for the same reason. Probably this doesn't happen in practice, but can happen theoretically. Signed-off-by:

Fix the maximum size of the coredump generated with current mt7921 firmware. Otherwise, a truncated coredump would be reported to userland via dev_coredumpv. Also, there is an additional error handling enhanced in the patch to avoid the possible invalid buffer access when the system failed to create the buffer to hold the coredump.
